SIDECIFICATION forming part of Letters Patent No. 464,865, datedDecember 8, 1891.

Application ledApril 20, 1891. Serial No. 389.665. (No model.)

To all whom it may concern:

Be it known that I, CARL GUELICH, of 0ttawa, in the county of Franklinand State of Kansas, have invented anew and Improved Burglar-Alarm, ofwhich the following is a full, clear, and exact description.

The object of the invention is to provide a new and improvedburglar-alarm which is simple, durable, and compact in construction, canbe readily carried about and set up in a room or other desired place,and arranged to instantly give an alarm in case the door or window ofthe room or other place is opened. The invention consists of certainparts and details and combinations of the same, as will be fullydescribed hereinafter, and then pointed out in the claims. l

Reference is to be had to the accompanying drawings, forming a part ofthis specification,

in which similar letters of reference indicate corresponding parts inboth the figures.

Figurel is a front vi ew of the improvement as applied in a room, andFig. 2 is an enlarged transverse section of the improvement.

The improved burglar-alarm is provided with a suitably-constructedcasing A, open at the front and provided on its upper end with a hangerB, adapted to engage a hooked nail or other convenient projection in aroom; or it may be engaged by a gimlet C, screwed into the wall of theroom at the desired place. Within the casing A is secured a `bell D,adapted to be sounded by a striker E, fulcrumed on a rod F, secured inthe casing. The lower end of the striker E is formed with a slot E',engaged by a crank-arm G, formed on a shaft II, mounted to turn insuitable bearings in the casing A and provided on its outer end with ahandle I. Un the shaft H is secured or formed adrum J, arranged withinthe casing A and on which is adapted to be wound a cord or rope K,passing through an opening A in the bottom of the casing A. The end ofthe rope or cord K is connected with a weight L, preferablyin the shapeof a ball, the said weight being also connected with one end of a stringN, preferably a black silk' thread fastened on a gimlet O, adapted to bescrewed into the door, window, or other place, so as to stretch thestring across the path likely to be taken by a burglar or otherunauthorized person. f

rlhe device is used as follows: The casing A is secured to a suitablepart of theroom or other place, as described, and the cord or rope K iswound up on the drum J, the weight L being placed in the bottom of thecasing, as is plainly indicated in Figs. l and 2. The string N,connected with the weight, is stretched across the path of the burglar,the gimlet O being screwed in the door, window, or other article, sothat the string N is taut, as is plainly illustrated in Fig. l. Now whenthe burglar moves against the almost invisible cord or string N then thelatter pulls on the weight L, so that the weight is pulled off of itsresting-place in the casing A and falls down, thereby pulling on thecord or rope K,

so that the drum .I is revolved. The revolving of the drum .I causes arotation of the shaft H, which, by its crank-arm G, imparts a swingingmotion to the striker E, so that the ball on the striker sounds the bellD, thus giving an alarm. It will be seen that the bell is sounded untilthe weight L in its descent has completely unwound the cord or rope fromthe drum .I or has reached the floor. It will further be seenV that thedevice is very simple and durable in construction and can be readilycarried about in a trunk or valise to be conveniently set up in a roomin a hotel or other place.

IE the gimlet O is secured on a door or window and the burglar in orderto make an entrance opens the door or window, then a pull is exerted onthe string N and the weight displaced, so that the alarm is sounded, asabove described.

I-Iaving thus fully described my invention, I claim as new and desire tosecure by Let-ters Patent-n 1. In a burglar-alarm, the combination, witha casing, a bell in the casing, a pivoted striker, a drum, and means foractuating the striker from the drum, of a cord or rope wound on thedrum,a Weight connected to said cord or rope and resting normally in thecasing, and a string or cord connected to the weight and by which theweight iswithdrawn from and resting normally on the bottoni of the thecasing to actuate the drum,substanta.lly

as described.

2. 'In aburglara1arm,the combination,\vith 5 a casing and a belltherein, of alJ pivoted striker having a slotted lower end, a shaft',mounted in the casing and provided with a. crank engaging the slot ofthe striker, a drum on the shaft, a rope or cord Wound on the ro drum, aweight on the end of the cord or rope easing, and a string or cordsecured to the Weight and by which the Weight is withdrawn from theeasing to actuate the drum, substantially as herein shown and described.

CARL GUE LICH.
